Q:Color steel sandwich panel 75 (0.5 / 0.3) × 1200/1000 said what: 75MM thick core material, bilateral color plate thickness 0.5MM and 0.3MM, 1.2 meters wide or 1 meter wide board.

Q:What is the level of fire protection for the production of polyurethane sandwich panels?: Class C plant.

Q:Is the polyurethane sandwich panel and foam board flame retardant?: On the market, the polyurethane foam flame retardant grade B1, B2, B3 three grades. Because of the cost, sandwich board with the majority of polyurethane material is B3 level, a small amount of B2 level, there are a small amount of special requirements B1 level. B1 level for the 'flame'; B2 level for the 'combustible'; B3 level for the 'flammable'. B1 grade oxygen index requirements of more than 30%; B2 level requirements of more than 26%, 26% of the following collectively referred to as B3 level. You said the flame retardant, it should be self-extinguishing from the fire. B2, B1 from the heat certainly no problem. A little better B3 (oxygen index of about 25%) can also be self-extinguishing, but more than B2 self-extinguishing time more than a few seconds. General oxygen index of less than 24%, it is difficult to self-extinguishing from the fire, will always burn, the greater the greater the burning. The The Oxygen Index: The concentration of oxygen required to stabilize the combustion in the oxygen and nitrogen gas mixture under the specified shape of the foam, the specified source of fire and the size of the flame. - For example, the better the flame retardant properties of the foam, the higher the concentration of oxygen needed to ignite the foam, the higher the oxygen index of the bubble

Q:Rock wool sandwich board standards which: Up and down the surface: the use of galvanized color steel plate, the thickness of 0.4-0.8mm. According to the specific requirements of customers, can also be used galvanized steel or galvanized steel plate. The steel plate is first molded by a molding machine and is compounded with the rock wool factory.

Q:What brand of rock wool sandwich board is good: Shandong Yongguang building materials technology companies to produce rock wool composite board has more than 10 years of history, is located in Jiangbei largest steel production base - Zibo Zhoucun, color steel plate, rockwool core material, such as a complete upstream and downstream industry chain, Has an unparalleled low cost advantage. Save money is the last word! Welcome to the majority of steel installation company to visit.

Q:EPS corrugated composite board and corrugated sandwich board What is the difference, 50MMEPS corrugated composite board (0.5 on the next 0.4) to do the plant roof construction process is how The price is almost a square?: EPS corrugated composite board is a corrugated sandwich board, according to the core of the different corrugated sandwich panels are divided into EPS corrugated sandwich panels (that is, EPS), extruded sandwich panels, polyurethane sandwich panels and rock wool sandwich Plate and so on. Construction is the steel structure plus sandwich panels.

Q:With a foam sandwich board made a 72 flat house, the cheapest how much money: It depends on how high your house, the color plate is calculated by the board area, calculate the material about 90 or so per square

Q:Is the rock wool sandwich panel fireproof?: Fire, Class A. Now for the external wall of the rock wool board without composite can be, and is a thin plaster system

Q:Magnesium Sulfide sandwich color steel plate: Henan Ming-chen purification Technology Co., Ltd. mainly produces and sells magnesium sulfate fire board, magnesium sulfide mechanism board, magnesium sulfide manual board, purification equipment (return window, diffuse board, medicine cabinet, purification lamp, color steel plate series, Purification of special aluminum, plate exhaust, residual pressure, air conditioning units, ozone generator, efficient air supply, air filter, laminar flow hood, clean sampling vehicles, transfer window, air self-purification, air shower), to undertake purification engineering. I uphold the company in good faith-based, quality-oriented, service-oriented concept for the majority of customers to provide quality services.
